Implement functionality for custom images for air gap deployment

[misohu]

Context

We want to unify implementation for handling custom images in the charms. We can implement key functions like parse_image_config (example here) and get_images (example here).

Note: There might be two versions for for get_images where one does not handle splitting the images into name and tag and the other one is handling it.

What needs to get done

Implement the:

• parse_image_config function
• get_images function which can be share across charms. Make sure the functions are properly tested.

Use the functions in target charms. List (may not be complete please double check):

• kserve.
• katib charms.
• kfp-operators.
• notebook operator. Note: this is little different as we are populating the drop down with the list in config.
• Please check if I have missed something.

Definition of Done

1. Functions are implemented tested and merged
2. Function from chisme is used in the charms

Process information: We have decided in this PR https://github.com/canonical/kfp-operators/pull/416 that we will not implement this feature as the fix implemented in that PR is timely pressured (there was not enough time to implement the feature and deliver the fix).
